And you expect many/any to have time to spend helping make a forum, something which hardly anyone would happen to know about, and give such little info about what sort of help, what sort of forum you're aiming for, etc? =/ Can't say you were likely to find anyone like that in the first place.
Well, there are plenty of forums for both of those out there. If you choose something that's done a lot, you also have to come up with a way to make your forum stand out from all the others. You have to come up with something different you can offer that nowhere else does to draw visitors.
